All 3 bleed air switches were OFF and had not been moved by the impact - expanding on this would have spoilt the tidy little scenario.
It has since come to light that the pilots had selected both audio switches to MASK implying that they probably did don their masks at some stage - going to MASK is something pilots often forget to do.
Oh yes, and it has now been shown beyond reasonable doubt that the PMS was in AUTO at impact anyway.
The Court was told all of this but it evidently didn't fit the guilty verdict neatly enough.
It may be of interest to you that the Greek investigators never bothered to access the pre-impact status of any of these switches.
